Why does the sound of a Mosquito (high frequency sound system) linger in my ear?

Answer

Hello,

The human ear can perceive frequencies between 0 and 20000 Hz (Hz=vibrations per second). Depending on age, or exposure to high-intensity sounds, hearing sensitivity decreases. Our brains try to compensate for this decrease in sensitivity by “amplifying” the stimuli to come. You can better see that strengthening as “paying more attention to”. An example of this is tinnitus. The brain is simply capable of receiving sounds in a certain frequency range and with a certain intensity. When those sounds disappear, the brain will increase the “amplification”. In the absence of input stimuli, the brain simply generates them itself. This is the case when the ear has been “overloaded”. In some cases permanent hearing damage can occur.
